Michigan is beginning to see the fruits of its labor with regard to graduate transfer Calvin Anderson.

The 6-foot-5, 300-pound left tackle from Rice has reportedly narrowed his list of potential schools to five, with Michigan and Texas identified as his "first tier" options," Anderson told Sports Illustrated on Thursday.

SI's Bruce Feldman reports Anderson is also considering Auburn, Oklahoma and TCU, in that order.

"He has set a deadline to make his decision by March 25th -- the day he turns 22 -- but adds that he'll likely make his decision before then," Feldman wrote.

The Michigan coaching staff -- head coach Jim Harbaugh and offensive line coach Tim Drevno included -- made a beeline for the state of Texas last month, an attempt to court the three-year starter at Rice. Drevno has since gone back, and Anderson took an official visit to Ann Arbor last weekend.

Today was an incredibly productive day! These outstanding coaches gave me further clarity on just what they each have to offer, and I'm excited to be choosing from such an excellent selection of programs. I am one step closer to finding my 2018 season home! pic.twitter.com/1XDZ3znH8W

Anderson would give Michigan a reliable option along the offensive line. He's started an impressive 36 straight games at left tackle for Rice and earned honorable mention all-Conference USA honors the last two seasons.

In 2017, the Owls had the 38th best rushing attack in the country while ranking 90th in sacks allowed (29) and 96th in tackles for loss (78).
